METHOD OF MANUFACTURING BOOTS AND SHOES.

Application led April 12, 1926. i Serial No. 101,248.

'This invention relates to an improvement in boots and shoes and the method of manufacturing the same.

The object of the invention is to provide a boot or shoe which in its preferred form embodies a rubber upper which is cemented to a. leather insole and a leather welt and which has a leather outsole sewed to 'the leather welt, the construction being particu- 0 larly adapted for rough usage and for use In deep snow, such, for example, as a lumbermans boot, but While being particularly adapted'for this use, it is, of course, not confined to such use but is equally well adapted 5 to ordinary use and conditions. The object of the invention is further to provide a boot which is watertight and which, having a leather insole and a leather outsole, is more comfortable and does not draw the 0 feet as much as a boot constructedentirely of rubber would.

The object of the invention is further to provide a boot or shoe of the character set forth which can be manufactured so as to 5 have a smooth, comfortable inner sole, the shoe being so constructed that there will be no tacks or threads next to the foot, the inner sole will be smooth and so incorporated in the shoe that the edges cannot curl up and 3 cause discomfort to the wearer, and also, the

construction of the shoe is such,vand the inner sole is so incorporated in the shoe, that a smooth and firm contour is given to the shoe adjacent the sole.

5 lThe shoe is of the type known as a welt shoe, but incorporated in the shoe is an intermediate sole and an inner sole, the inner {sole being of larger area than the intermediate sole, so that it projects beyond the 0 intermediate sole entirely around the same and the inner sole is lasted over the edge of the intermediate sole, and its marginal portion contacts with the outer surface of the marginal portion of the intermediate sole.

5 The invention further has for its object to produce a shoe of the character hereinbefore set forth, but embodying therein a cushion sole interposed between the inner and in termediate soles.

0 The invention consists in the improved boot or shoe and the method of manufacturing the same hereinafter set forth in the specification and particularly pointed out in the claims.

Referring to the drawings y Flgure 1 is a sectional View taken transversely of a shoe embodying our invention and illustrating the first step in the method of manufacturing the same.

Fig. 2 is a transverse section showing the last inserted in the shoe illustrated in Figure 1 and with the shoe and last inverted.

Flg. 3 1s a transverse section of the completed shoe.

Fig. 4 is a transverse section of a completed shoe similar to that illustrated in Fig. 3 and embodying therein a cushion sole interposed between the inner and intermediate soles. Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, Figures 1 to 3, 5 is the upper of the shoe which is preferably constructed of rubber. 6 is the Welt and 7 the Inner sole, the welt and inner sole being preferably of leather. 8 is the intermediate sole, 9 a filler of waterproof material, 10 the outsole, preferably of leather, and l1 the last.

Figure 1 illustrates the shoe as it appears after the first operation, in which the upper 5 is cemented to the inner sole 7 and also has the welt 6 cemented thereto for a portion of the width of the welt, as for example, between the dotted lines a and b, Figure 1; thus the welt and the inner sole are attached independently of each other by adhesive material to the marginal portion of the upper, the welt contacting with the outer face of the marginal portion of the upper and the inner sole contacting with the inner face of the marginal portion of the upper.

The next step in the method of manufacturing our improved shoe is to introduce the last 11 therein and then place the intermediate sole 8, which is also preferably of leather, upon the inner sole 7, as illustrated in Fig. 2, andattach the intermediate sole to the inner sole by cement, or any adhesive material.

It will be noted that the inner sole is enough larger than the intermediate sole to project beyond the edge of the intermediate sole to a suiiicient extent to enable the inner sole to be attached to the upper and to the welt and then folded around the edge of the intermediate sole, the welt being cemented to the upper for only a portion of its width is allowed to extend out around the upper as is then sewed to the welt illustrated in Fig. 2 to a sufficient extent to permit attaching an outsole 10 to the lip of the Welt by stitches, or in any desired manner, and with the marginal portion of the inner sole contacting with the outer face of the marginal portion of the intermediate sole.w

The lasting operation is preferably performed in a similar manner to that illustrated and described in the Patent No. 718,873, issued to Richard W. Peer on January 20, 1903 entitled Machine for lasting boots or shoes, or the lasting operation may be performed by hand in the usual manner or by a lasting machine embodying pinchers, as in the hand-method lasting machine of the United Shoe Machinery Corporation, or the shoe may be lasted by means of wipers, any of these different methods of lasting being well known to those skilled in the art.

When the shoe is lasted by means of a Wire attached to the combined upper, inner sole and Welt and the ends of the Wire drawn in until the upper has been drawn closely over the last at all points, a specially devised hand tool is desirable, one end of which can be easily inserted under the combine-d upper, welt and inner sole, asthe machine or hand tool draws in the Wire which pulls over the combined inner sole, upper and welt. A smoother and neater lasting can be thus accomplished.

After the shoe has been lasted as hereinbefore described, a filler 9, see Fig. 3, is introduced in the space between the oppositely disposed edges of the inner sole, upper and Welt and in contact with the outer face of the intermedia-te sole, and the outer sole 10 by stitches 13 in a well-known manner.

The filler 9 is preferably of waterproof material and therefore by reference to Fig. 3, it will be seen that as the rubber upper is cemented to the inner sole and to the welt no water can pass through, the interior of the upper being completely sealed against the passage of Water thereinto.

It will be understood .that the upper, the

. gether from the point Where the breast of the heel would. come in the finished shoe on one side around the toe of the shoe upper to a point where the breast of the heel would come on the opposite side of the inner sole, or the upper, the inner sole and the welt may be cemented together around their entire contour.

In Fig. 4 our invention is illustrated as embodying therein the construction hereinbefore set forth and particularly illustrated in Fig. 3, but in addition thereto a cushion sole is interposed between the inner and intermediate soles.

Referring to Fig. 4, 5 is the upper, 6 the Welt, 7 the inner sole, 8 the intermediate sole, 14 a cushion sole, 9 the filler and 10 the outsole. This embodiment ofour `invention is manufactured by the same method as hereinother suitable material, and may be attached to the Welt by sewing, cementing, stapling, or any other suitable method of attaching.

We claim:

1. A method of manufacturing boots and shoes which comprises, first, cementing a. welt and an inner sole to the marginal portion of a rubber upper with the Welt on the outer face of the upper and the inner sole on the inner face thereof, second, placing an intermediate sole adjacent to the inner sole after placing a last in the upper, and third, lasting the upper over the intermediate sole with the marginal portion of the inner sole folded over the edge of the intermediate sole and into contact with the outer face of the marginal portion thereof, and with the Welt on the outer face of the up er.

2. A method of manufacturing boots and shoes which comprises, first, cementing a welt and an inner sole to the marginal portion of a rubber upper with the welt on the outer face of the upper and the inner sole on the inner face thereof, second, placing an intermediate sole adjacent to the inner sole after placing a last in the upper, third, lasting the upper over the intermediate sole with the marginal portion of the inner sole folded over the edge of the intermediate sole and into contact with the outer face of the marginal portion thereof and with the welt on the outer face of the upper, and fourth, fastening an outsole to the Welt. l

3. A method of manufacturing boots and shoes which comprises, first, cementing a welt and an inner sole to the marginal portion of a rubber upper with the welt on the outer face of the upper and the inner sole on the inner face thereof, second, placing a last in the upper and attaching an intermediate sole to the inner sole, third, lasting the upper over the intermediate sole with the marginal portion of the inner sole folded over the edge of the intermediate sole and into contact with the outer face of the marginal portion thereof and with the Welt on the outer face of the upper, and fourth, introducing a filler in the space between the oppositely disposed edges of the inner sole, upper and welt and in contact with the outer face of the intermediate solle, and fifth, attaching an outsole to the We t.

4. A method of manufacturing boots and shoes which comprises, rst, cementing a welt and an inner sole to the marginal portion of a rubber upper with the Welt 0n the outer face of the upper and the inner sole on the inner face thereo` placing a cushion sole adjacent to the inner sole, and an intermediate sole over the edges of the cushion and interme- 10 diate soles and into Contact With the outer face of the marginal portion of the intermediate sole and with the Welt on the outer face of the upper.

In testimony whereof We have hereunto set 15 our hands.
